Spectral Properties of Condensed Matter

Abstract

In the visible range of the spectrum we are familiar with the perception of colour, which arises if the surface of a material reflects the natural light in one part of this spectrum more strongly than in others. The light which is not reflected penetrates into the material and will eventually be absorbed. Among the most important media observed in remote sensing applications on the earth’s surface are those which are composed, for a considerable part, of organic molecules.
